The lighter wouldn't make an difference but taller would a little but it will also make speedo read wrong
A bigger trans wouldn't change anything in fact it would weigh more and probably cause you to lose mpg. If the present trans doesn't have an overdrive, replacing it with one that does would increase mpg.
To increase mpg by eliminating weight. The vehicle weighs less than 1000 lbs and gets up to 70 mpg.
My research has shown that if you don't add bigger wheels and tires the gas mileage will stay about the same. Maybe at worst you might lose 1/2 of a mpg.
Kinda-sorta. Small changes are OK, but mess with the wheel size enough and the load on the engine will change(it'll be like driving in the wrong gear) which will hurt the MPG. Also, you don't want to go crazy wide either, as that will affect rolling resistance. With higher rolling resistance you get lower MPG.
ninjas are lighter and the the nitro decks are wider
Multiply mpg by 0.43 to get kpl
depending on how you drive, these shoes on wheels get between 16-20 stock.
it really depends on the size of wheels and tires that are put on it.
The 1999 Tracker averages 25 mpg in the city. The tracker averages 28 mpg on the highway. These are estimates, the mileage can change with driving conditions.
32 miles per gallon = 38.4 miles per Imperial gallon.
bigger engines now, tuned differently, heavier, more accessories(added weight)
